Application filed March 3, 1908. Serial No. 419,051.

To all whom it may concern:

Be it known that I, ADELBERT S. GAY, a

citizen of the United States, residing at Binghaniton, in the county of Brooms and State of New York, have invented certain new and useful Improvements in Horseshoe-Calks, of which the following is a specification.

My invention relates to improvements in horse-shoe CitlliS and to the means. of holding the calks in a horseshoe. The objects of my improvements are-1st, to provide a secure means for holding in horseshoe, adjustable or removable horseshoe calks, 2nd, to provide adjustable horseshoe calks for a horse-shoe which callrs have a ribbed surface, so as to prevent the horse enlarged longitudinal section of the toe call:

when taken on line 2, 2, of Fig.1. Fig. 3. is a transverse section of same on line 3, 3, of Fig. 2. Fig. 4. is a sectional view taken on line 4, 4, of Fig. 1. showing one of the heel cells. Fig. 5. is a sectional view of the same taken on line 5, 5, of Fig. l. Fig. 6. is an inverted plan view of a modified form of the calk. Fig. 7. is a transverse section on line 7, 7, of Fig. 6. Fig. 8 is a sectional view of a modification of my invention.

Similar characters refer to similar parts throughout the several views.

In my device the toe call; and heel callrs are described as follows.

The toe calkis provided with a base, 23,

and from which. base -3, projects a curved tenon 1. This curved touch is provided with two screw holes 4, 4 The edge of the toe calks is provided with ribs a, a, a, a and a as showirin Figs. 2 and 6. These ribs project from the outer surface of the call; and run alternately from the outer to the inner and from the latter to the outer edge of the calk, as it stands in position on the horse-shoe plate. These ribs a, a, a, present a longitudinal level surface, parallel with the inner surface of the shoe plate while the surface of the two outer ribs a, a, of the call; project on an incline downward and backward from the this tenon are curved as shown in Figs. 2 and 3. The side 6 of the mortise is vertical from its upper edge downward to near its lower edge, and is then curved outward and down Wardtoward the lower edge while the side 6 extendsupward first in a curve and then in a verticalline S to the upper surface of the shoe. The tenon 1 of the calli slips into'place by a curved movement around the curved side 6 of the mortise. In order to insert the calk in place it is tipped slightly back toward the arch of the shoe.

The curved side 6 of the mortise is'provided with two indentations or holes 8, 8,

rejected in a diagonal direction into the edge 7. Through the curved side 6 of the mortise are projected diagonally two screw holes 9, 9, extending likewise diagonally through the tenon as shown by -9 9" Through these screw holes are inserted the screws 10, 10 which screws pass through the surface of the shoe and through the tenon of the call; and into the indentations 8, 8, and thus aid in securing the calk tenon firmly within the mortise.

The heel oalks are described as follows, a description of one sullicing for both. The heel oalk is provided with a base 11, 11, and from this base projects the curved tenon 12. This curved tenon 12 is provided with a screw hole 13. vided with the mortise, having the curved sides 15 and '16 and 17 and 18 as shown in Figs. 4 and 5( The sides 15 and 16 of Inortise 8 are curved or. flared at their lower end toward the lower edge of said mortise and then curved upwardly in approximate J-form with the upper end of the le of tired terminating vertically as at 20, the rear upper extremity thereof curving somewhat rearwardly. The tenon of the heel call: sli s into place by a curved movement around ,t is curved side 15 of the mortise in order to insert either of the heel calks into )lace, the calk is tipped slightly backtowar or in the direction of the crown of the shoe plate. Through the end of each heel of the shoe plate is projected the screw hole 21 and into this is inserted the screw 22 011 a line parallel with the upper and lower surfaces of the shoe plate. This screw 22 thus extends through the heel of the shoe late but by means of the Each heel of the shoe is proits screw hole .21 exten s into the tenon body of the heel call: as shown in Fig. 4. .This operin itsmortised position. This construction of the tenon of the heel palk enables it to be inserted into the. shoe plate in the same manner that the toe calk is inserted. The up er 5 surface or edge of the heel calk is provi ed likewise with the ribs a, a, and a, a as shown in Fig. 5. These ribs project from the upper or outer surface of the heel calk and run alternately fromthe back to the front side of the calk and from the latter to the back side of the calk in a zig-zag line as it stands in position on the horse shoe plate.

- Attention is called to the angle of the inner screw hole 8" in ledge 7 of the mortise as 5 shown in Figs. 3 and 8 and to the angle of the screw hole 13 in the heel calk as shown in Fig. 4. The screw hole 8 in ledge 7 of the mortise is at a different angle from that of the screw hole 4 in tenon 1. Hence as the point of the screw 10 enters hole 8 in ledge 7, it is forced against the upper side of hole 8 and. the screw is thereby held down firmly against the shoulder of the calk. Hence by further turning of screw 10 it is tightened against the upper side of hole 8 The screw hole 13 in tenon 12 of the heel call; as shown in Fig. 4, is at a difierent angle from that of screw hole 21 in the heel and the screw 22 as it is turned down to place, .bears against the upper side of screw hole 13 in tenon 12 of the heel calk thereby drawing the shoulder of the calk up firmly against the lower surface of the shoe late.

As a mo ified form of my invention I have the toe calk shown in Fig. 6 and Fig. 7. This toe calk is provided with a base 24, and from which base 24 projects a curved tenon 25. In the center of this curved tenon and,

curving 1n an opposite direction from the 40 curve of tenon 25, there is projected the curved tongue 26; the edge of the toe calk in this form of my invention is provided with ribs a, a and a, a the same as shown in Figs.

1 and 2. These ribs project from the outer surface ofthe calk and run alternately from the inner to the outer edge of the calk in a zig-zag'conrse 'as it stands in position on the horse shoe plate. These ribs a, a present a longitudinally level surface parallel with the to inner surface of the shoe plate while the surface of the two outer ribs a; a of the calk, project on an incline downward and backward from the front edge of the calk as shown in Fig. 7. p In this modified form'of my device the'toe of the horse shoe is rovided with the mortise 27, the front si e of the mortise having extended through it the semicircular o 'ening 28. The tenon 25 of the toe calk 0 this modified form of my invenac tion, slips into place b a curved movement around the curved si e of the mortise 27;

' but in order to insert the toelcalk in place'it is ti ped slightly forward toward the crown of tie shoe as the tenon moves down to its place the tongue'26 passes down through the opening 28 and when the calk is in lace it is in the position as shown in Fig. 7. 'l irough the opening 28 may be inserted a screw or plug which, when in place, will bear down upon the tongue 26 and thus aid in holding the toe c alk firmly in place. I

By this peculiar construction of the tenons in the first form of my invention described herein, it renders it impossible for them to be pulled out or the calks loosened. 7

Having thus described my invention, what I claim as new and for which I desire Letters Patent is as follows: 7
